What we are looking for

• Degree in Computer Science, Computer Engineering, Mathematics or related discipline, or equivalent practical experience;

• 8+ years of experience in software engineering, AI/ML engineering, low-code automation or solution architecture, including 2+ years of hands-on Generative AI delivery and technical leadership at team level;
